Working with adversaries is core to Trump's success. Maybe not so much in business (hard for me to say about that) but in politics if you don't work with your adversaries, nothing gets done.
The best and most obvious recent example is Biden's approach to Russia. Take all the media's lies about Trump and Putin out of the equation, and simply realize that Biden's approach was nothing more than leading to a long and slow and painful demise for Ukraine.
Sure, if they have to give up what they'd rather not give up in order to get peace, that sucks. But the killing would stop, which is pretty much the opposite of what sucks. Even if temporarily with a cease fire. And that is something that Biden's approach could never accomplish, while Trump's approach very well may.
